NON-REFILLABLE BOTTLE.

SPECIFICATION forming part of Letters Patent No. 761,362, dated May 31,1904.

Application filed October 24, 1903.

'10 cpl/l whom it may concern.-

' vide a simple and effectivearrangement of the the flanges together.

parts which constitute such non-refilling device and' to so positionthem that there will be a full and unrestricted flow of liquid from thebottle when pouring therefrom.

.A bottle embodying my invention is illustrated in the accompanyingdrawings, in which Figure 1 represents a vertical transverse section ofthe bottle, and Fig. 2 a bottom plan view of the hood or cap-piece Gremoved.

Like letters of reference refer to like parts in the two figures.

A represents the main or body portionof the bottle, provided at the topwith a short outlet-neck a. To this body portion is attached a neckportion B, the two parts being fastened together'by a joint of suchnature that it cannot be readily broken or when once broken the partscannot be easily put together again without special appliances. Thisjoint, 'as I propose to make it, comprises annular flanges at the topand bottom of the parts A and B,

respectively, where they come together, with a rubber or other gasket 0placed between. In joining the parts together after the body portion hasbeen filled with the liquid the neck portion B is set in place andpressed down so as to compress the gasket C between the flanges on thetwo parts. A metal flanged ring- D is then slipped down around theflanges and pressed in at top and bottom to firmly clasp 'It will beevident that this form of joint cannot be broken and put together againwithout special appliances, for in removing the ring D said ring will beeither broken or so mutilated as to prohibit its being used again,thereby necessitating the use of a new ring, which, moreover, requiresspecial Serial No. 178,342. (No model.)

tools for fitting it into place. The joint between the parts as so madeis firm and tight and there can be no leakage of air or liquidtherethrough. While Ihave described this as my preferred manner ofjoining the parts, I do not desire to be limited in this respect, as theparts may be otherwise sealed together without departing from the spiritof my invention.

The non-refilling device consists, primarily,

, of the hood or cap-piece G, whichcovers and surrounds the neck a ofthe body portion A, the base of the hood being placed below the top ofsaid neck and spaced away from it so .as to'provide a passage for liquidaround the base into the neck portion B. As illustrated, this hood issubstantially conical in shape and is secured to the neck a by ascrew-threaded ring H, to which it is attached by means of a number ofwebs'I. The hood, however, may be otherwise shaped and may be secured inplace with relation to the neck a inother ways. 1 The outlet throughneck ais provided at the outside with a valve E, said valve beingprovided with wire guides F to keep it in place when opening andclosing. Resting upon the valve within the hood is a ball J of somelittle weight. The valve E and hood G may be of glass or any othersuitable material, and I preferably seat the valve upon the rim of necka upon a knife-edge, as indicated, in order'to prevent the valve fromsticking thereto.

In use when pouring a liquid from the bottle upon turning the bottle onits side the weight of the liquid will throw the valve E and. ball Joutward into the hood G, allowing the liquid to run out from the neck ainto the hood and around the lower edge thereof into the neck portion B,air passing in around that the body portion A. If it be attempted torefill the bottle when lying on its side, the ball J, resting as it willagainst the inclined sides of the hood G, will press the valve E againstits seat and hold it there, the weight of the liquid which is attemptedto be run in through the neck B also assisting in pressing the valve toits seat. Even without the valve and ball the hood G, by reason of itsposition with relation to the neck a, will prevent the bottle from beingrefilled in the ordinary ways of pouring in through the neck, since thebase of the hood lies below the top of neck a and forms a trap whichprevents the escape of air from the body portion. Some liquid may beforced into the body portion by immersing the bottle on its side in abath of the liquid when the hood only is used; but the bottle cannot bemore than half-filled in this way, and it will not be worth while. Bythis arrangement it will be seen that I have produced an effectivedevice for preventing the refilling of the bottle, such deviceconsisting of a minimum number of parts very simple in theirconstruction and manner of operation. A bottle so constructed willeffectually prevent the adulteration of the contents of the body portionA or therefilling thereof when once emptied, since for practicalpurposes no liquid can be run into the body portion without removing theneck B and hood G. Moreover, it will be observed that there is a fulland clear passage for the liquid through the neck B and amplepassage-ways from neck (0 around the hood into neck B, so that therewill be the same freedom of flow as in an ordinary bottle.

Having thus described my improvements,

7 what I claim as my invention, and desire to secure by Letters Patent,is

1. In a non-refillable bottle, a body portion closed at the top by ahead provided with an outlet at its center, a neck portion having aflaring base secured to the body portion at the outside diameter thereofby a sealed joint, and means for preventing the entrance of liquid fromthe neck portion into the body portion through said outlet, said meansbeing inclosed within the flare of the neck portion and separatedtherefrom to form a clear passage-way between.

2. In a non-refillable bottle, a body portion closed at the top by ahead at the center of which is an outlet surrounded by a short neck, aneck portion having a flaring base covering said head and secured to thebody portion by a sealed joint, a valve to close the outlet through saidhead, a substantially conical hood or cap above the on tlet-neck, therebeing a passage for liquid from said outlet to the neck portion aroundthe base of the cone, and a ball within the cone to press the valve toits seat.

3. In a non-refillable bottle, a body portion and a neck portion, thebody portion having an outlet into the neck portion, and a hood or capwithin the neck portion covering said outlet, the base of said hoodbeing positioned below the top of said outlet and there being a passagefor liquid from said outlet to the neck portion around said base.

4. In a non-refillable bottle, a diaphragm below the flare of the neckprovided with a central orifice, and a hood or cap positioned abovesaidorifice, the base of said hood being located below the top of saidorifice and forming a passage-way for liquid from said orifice to theneck around said base.

In testimony whereof I have afiixed my signature in presence of twowitnesses.
